Microbiome sequencing has come so far in 2 decades. In my PhD— I used TRFLP…. am now doing long read sequencing of entire soil metagenomes! This review was great fun- thanks Gitta Szabó @emileyeloe-fadrosh.bsky.social Tanja Woyke of @jgi.doe.gov www.nature.com/articles/s41...

Agricultural liming helped create the infrastructure that enhanced weathering needs to scale up, but it also makes some enhanced weathering projects harder to support in the carbon market. We show why this tension exists and discuss some paths forward in our latest article.

If you're submitting an #AGU2025 abstract on #enhancedrockweathering biogeochemistry, microbiology, hydrology, modeling, MRV, public policy or social science, consider session B037, Enhanced Weathering for Carbon Dioxide Removal & Improved Soil and Agronomic Properties -due 7/30!

✨Paper #2 has just been published @weareagc.bsky.social ✨ And it is about hopanoids!! Thank you @climategordon.bsky.social for trusting a brand new journal with your research. AGC is 💎 open access: free to publish and free to read 🙌 Geochemists, come publish with us! journals.uu.se/AGC/article/...

Check out our new pre-print on how to use soil mass balance (“TiCAT”) to quantify rock dissolution in enhanced weathering trials. Includes key do’s & don’ts, a deep dive into signal-to-noise (constrained in data from from 5 sites), and open-source code to try it yourself. Feedback welcome! #EW #CDR

Efficacy of seaweed-based carbon dioxide removal reduced by iron limitation and nutrient competition with phytoplankton. cdrxiv.org/preprint/385

Introducing CDRXIV, a central hub for preprints and data on carbon dioxide removal (CDR). Our goal is to make it easier for CDR research to be shared and discovered by researchers in academia and industry. CDRXIV was built by @carbonplan.org. Read more about it here: carbonplan.org/blog/cdrxiv-...

Soil cation storage is a key control on the carbon removal dynamics of enhanced weathering. cdrxiv.org/preprint/351

Direct measurement of carbon dioxide removal due to enhanced weathering. cdrxiv.org/preprint/352

Cost of cooling: The value of reversible carbon storage in a zero-emissions world. cdrxiv.org/preprint/348

A new wastewater alkalinity enhancement protocol can be used to issue CDR credits to activities that don’t increase the amount of carbon removed from the atmosphere. We wrote about how this breaks with other CDR protocols, and what it could mean moving forward. carbonplan.org/blog/counter...

A Framework for Integrating Spatial Uncertainty into Critical Zone Models: Application to Enhanced Weathering. cdrxiv.org/preprint/334

There’s an ongoing debate over what should “count” as CO₂ removal. In a new commentary with @hausfath.bsky.social, we break down key points of contention, proposed definitions, and why no definition offers a perfect path forward. (1/5) carbonplan.org/research/def...

Photosynthesis in Rivers as a Loss Pathway for ERW-Derived DIC and Alkalinity. cdrxiv.org/preprint/329

I'm going to be at the #AAAS conference in Boston for the next few days. A big part of why I'm there is to talk to folks about the open-source data tools we build at @carbonplan.org. We're working on databases for investigating offsets, a new preprint server for CDR research, and more. Say hello!

Limited impact on oysters in first-of-its-kind field trial of marine carbon dioxide removal (mCDR) strategy. cdrxiv.org/preprint/326

The potential and cost of carbon dioxide removal using direct air capture with land-based wind and utility-scale photovoltaics. cdrxiv.org/preprint/310

If you're at AGU and want to chat open science in CDR (or just want a bagel and coffee) stop by the @cdrxiv.org breakfast this morning! 8:30-9:30 in Pod 1 of the poster hall!

Carbon Dioxide Removal research needs a central, multidisciplinary hub. We’re building it at cdrxiv.org. Read and download others' work, explore CDR pathways and topics, and help the platform grow by submitting your CDR research!
